a locating module configured to determine a location of the cleaning device in the area and to track movement of the cleaning device within the area;

a management module configured to receive data regarding the tracked movement of the cleaning device and to generate a graphical representation of a cleanliness level of at least a portion of the area based at least in part on the tracked movement.

2. The hygiene monitoring and management system of claim 1 , wherein the locating module determines the location of a wireless tag associated with the cleaning device based at least in part on strength of signals transmitted between the wireless tag and at least two access points.

3. The hygiene monitoring and management system of claim 1 , wherein the locating module is positioned on the cleaning device.

4. The hygiene monitoring and management system of claim 1 , wherein the graphical representation of the cleanliness level includes different colors corresponding to cleanliness levels of the area.

5. The hygiene monitoring and management system of claim 1 , further comprising a display on which the graphical representation is displayed, wherein the display is positioned on the cleaning device.

6. The hygiene monitoring and management system of claim 1 , wherein the cleaning monitoring system is configured to manage cleaning of the area via control of movement of the cleaning device in the area.

7. The hygiene monitoring and management system of claim 1 , wherein the management module automatically changes dispense of one or more chemicals in the area based at least in part on the location of the cleaning device.

8. The hygiene monitoring and management system of claim 1 , wherein the management module generates a notification to a user of a cleaning action to take when the cleaning device reaches a predetermined location in the area.

9. The hygiene monitoring and management system of claim 1 , wherein the area comprises a floor surface.

10. A method of hygiene monitoring and management, the method comprising:

a display module disposed on the cleaning device and including a graphical layout of the area, the display module configured to provide to an operator of the cleaning device information relating to cleanliness of the area based on the tracked movement of the cleaning device, the information including where to move the mobile cleaning device for a cleaning operation within the area based on the tracked movement of the cleaning device.

18. The hygiene monitoring and management system of claim 17 , wherein the locating module determines the location of the cleaning device based at least in part on strength of signals transmitted between the cleaning device and at least two access points.

19. The hygiene monitoring and management system of claim 17 , further comprising a cleanliness monitoring system configured to manage cleaning of the area based on one or more of a type of the area and a level of dirtiness in the area.

20. The hygiene monitoring and management system of claim 19 , further comprising a management module configured to receive data including the location of the cleaning device and the tracked movement of the cleaning device, wherein the data is transmitted to the display module, and wherein the management module automatically changes dispense of one or more chemicals in the area where the cleaning device is moved based at least in part on the location of the cleaning device.
